The Little Prince — original 1943 first edition, published by Reynal & Hitchcock in American English.

American English or the US English is the English language adapted in the United States of America. This language is the most widely spoken language in the USA and is de facto language used by the federal and state governments, to the extent that all laws and compulsory education presume English as the primary language. US English is explicitly given official status by 32 of the 50 state governments.
